This invention" relatos tov calendars of; the type coinprisine4 a strip of transparent material located over the datepad. cards or the like in a vertical or horizontal manner with e an adjustable date indicator slidably mounted thereon and having one or both"` ends 'fun nished' with earri'iling` slides adapted to engage, with the date pad or cards orwith guide bars or strips termed with or attached to the carrier for the date pad or cards;`

lin calendars ot the above type as previousconstriicted the slides have been secured to the ends of the transparent strip by means et staples, bv eyelets,` or by bendingr round the 'eid "oi24 the strip, to`r1nii`rsrA it with apertines, and providing the slide with projections` for enter-intr these apertures.

ic'cording to the present invention the slides are formed or provided with pointed 20 portions in suitable positions which are adapted to. pierce the material ot the transparent strip to hold the slide attac-hed thereto. 3 The slides imag7 be oli hoolelilre form as already known in such devices to engage over "a date pad, guide bar or the like and in some cases may have bent lugs or 'other means, of a ltnownllfind, for engagingl under the lower edge of a giiide bar or the like.

lin order? that `the invention may be better understood it will now be described with reference to the accompanying drawings in which:M

Fig. 1 is a perspective view ot one torin ot calendar made according to the invention.

Fig. 2 is an enlarged perspective view of the transparent strip and slide as used in the calendar shewn in Fig. 1.

Fig. 3 is a sectional elevation ot the upper portion ot the strip and slide shewn in 2.

Fig. 4 is a similar view to Fig. 3 but of a further torni ot the invention.

Figs. 5, 6, 7, 8 and 9 shew perspective views of* other modifications.

ln Figs. 1 to 3 which shew one particular form of calendar constructed according to the invention which comprises a strip 10 of transparent material such as celluloid havinpf one end bent back ou itself, the short arm 11 coming at the back. lhe slide is formed trom sheet inetal, tor instance ot brass ot light gauge and is ot the same width as the strip. Before bending into torni, the slide is oit rectangular shape the short side oi the rectangle being); the width ot' the transparent 5 strip and the longer side about twice the length of the short side.

lll

@ne end ot the strip is bent up at 12 and doubled bach on itself` the bent up' partv being about a ii'ttli of the total length ot the strip. This bent up. part has two or more points 13 strucknp theretroin and these points are directed towards the back portion 14; ot the strip, which opposite.the'points isiormed with depressions 15. i

The lower end'ogt the short arm. 11 o't the transparent strip 10 isl passed between the bent up parti 1Q oft the metal strip. and its haelt part 14 and suitable pressure applied to` the parts. This causes the points 13 to penetrate this part 11 of the transparent strip and by continued pressure or li ght blows, the points 13 which enter the depressions 15 contactwith the bottoms thereot and are bent outwards. 'llhc slide is thus ilrijnly secured to the transparent strip.

lhe other end 1G et the rectangular metal strip to term the slide bent downward-s so that it is adapted to, come over the bend ot the transparent strip.7 the upper portion ot the slide at the trent having a. 'groove termed thereon to. leave the upper end shaped as a somewhat'. civlindrical` finger or handle piece 17;

lin use the slide carrying the transparent strip 1GI is engaged over a dat@ @all SOIlDhlthe strip lies on the pad and is vertical whilst the other rear parts of the slide and strip 14 and 11 respectively come at the back ot the pad at the top. @n the strip is located the adjustable indicator 18 which is trictionally retained in position and the lower end of the strip 10 may it desired be bent up at 19 as shown to come at the back of the date pad or may be furnished with means to prevent the accidental removal of the indicator.

it' desired both ends oit the transparent strip may be furnished with a slide such as described and in this case the transparent strip may be arranged horizontally the slides having sufficient grip to hold the device in position on the date pad or the like.

ilVhere the slides are to engage around and under a guide or bar such as 2() (Fig. 1), the turned up part 1Q which is attached to the downturned end 11 ot the transparent strip 10 may not entend the full width of the slide but only occup7 the central portion leaving` two side tongues 21 one on each side which are adapted to come under the bar or strip 20 to maintain the device in position thereon.

lin place ot bending over the end or ends ot the transparent strip 10 to engage the slide bil) Cil

these ends maj7 not be bent over but may as shewn in one construetional form in Fig. 4 come between Vdoubled thicknesses 22 and 23 at the front of the slides one thickness having the points or the like 13 for perforating the transparent strip l() and the other if desired having depressions 15, apertures or the like co-operating with the points if desired.

According to another constructional form of the invention the transparent strip is utilized Without a slide or slides. In this form as sl'iewn in Fig. 5 both ends'of the slide are doubled 'or hooked over at 24 so that one edge engages around oneY edge of the date pad'or the like and the other edge around the parallel edge of the pad.

With a similar construct-ion but with one or both ends bent or hooked as shewn for example in Fig.V 6 the bent end or one of the bend ends or both, have a portion Q5 of the material of the transparent strip l0 struck up just before the' bend so that a tongue is formed Awhich constitutes a. manipulating handle. j l

' To increase the grip of the device on the datel pad or the like in this last mentioned form a thin sheet metalrslide such as 26 (Fig. 7) mav be provided consisting of a short doubled strip With a struck up tongue 27. This strip'QG comes on each side of the Vdate pad or the like' so that the portions thereof grip the pad andthe hooked vover end of the transparent strip is hooked over the slide so that'the tongue 27 of the slide passes through the aperture left in the strip 10 and comes adjacent the tongue 25 of the transparent strip.

As a further modification of this form and to adapt it to slide on a bar or strip the rear thickness of theslide 2G is formed on its lower edge with lugs or the like 2S shown dotted in Figs. 7 and 8 adapted to come lieloiv the lower edge of the bar or strip and thus retain the device in position.

Fig. 9 shews a form of the invention where an endless band or strip Q9 of transparent material entireljT encircles the date pad 30. IVith this construction the transparent inaterial to :form the strip can be made of lighter gauge than with previous constructions. The joint in the material preferably comes on the back of the date pad, the indicator 1S slidingin frictional engagement with the front.

The invention is not limited to the forms of calendars described or to the precise construetional details as these may be varied to suit particular cases.

IVhat I claim as my invention and desire to secure by Letters Patent of the United States of America is l. In a. calendar of the class described, a transparent strip rand a slide to cariv the strip, said slide having prongs integral therewith, extending through the material of the strip and securing the latter to the slide.

2. A calendar as claimed in claim l, in which the slide is hook shaped to engage over a suitable portion of a calendar pad.

3. A calendar as` claimed in claim 1, in which the slide is of hooked shape to engage over a. portion of a calendar pad and in which the rear edge of the slide is provided with lugs for engaging the calendar.

In Witness whereof I aiiix my signature.
